NAME

       plgdiori - Get plot orientation

SYNOPSIS

       plgdiori(p_rot)

DESCRIPTION

       Get  plot  orientation  parameter which is multiplied by 90 degrees to obtain the angle of
       rotation.  Note, arbitrary rotation parameters such as 0.2 (corresponding to  18  degrees)
       are  possible,  but  the  usual  values  for the rotation parameter are 0., 1., 2., and 3.
       corresponding to 0 degrees (landscape mode),  90  degrees  (portrait  mode),  180  degrees
       (seascape  mode),  and  270  degrees (upside-down mode). If plsdiori(3plplot) has not been
       called the default value pointed to by p_rot will be 0.

       Redacted form: plgdiori(p_rot)

       This function is not used in any examples.

ARGUMENTS

       p_rot (PLFLT_NC_SCALAR(3plplot), output)
              Returned value of the orientation parameter.
